Most likely, someone simply connected a hon-domain-member laptop or PC to
the network once, and it's gone now. The workgroup name will eventually go
away & not be visible. If you want to prevent stuff like this from
happpening in the future, you can either invest in a fancy-shmancy Ethernet
switch that won't give unauthorized computers an IP address, or do the cheap
& cheerful (and less effective) thing - disconnect any unused Ethernet jack
from your switch in the server room/closet/whatnot.
